Robot Tank is a 1983 video game for the Atari 2600. It was designed and programmed by Alan Miller and published by the then-fledgling Activision.
The game has the player remotely control a futuristic robot tank, whose mission is to stop enemy rebel tanks rampaging across the countryside from reaching downtown Santa Clara, California, United States. The tank is equipped with radar to locate enemy squadrons.
The game was innovative in that, instead of the player's tank being destroyed with a hit from an enemy, it was merely damaged, losing some capabilities such as radar or speed (enough damage would eventually destroy the tank). The game also features 24-hour gameplay (that is, combat could take place at any time of the day or night) and varying weather (rain, snow, fog), which added additional challenge in tracking enemy combatants.
The enemy is organized into squadrons. By defeating an enemy squadron, the player earns an additional reserve tank. The game ends when all of a player's tanks are destroyed.
